Hello and welcome Tjgg!
When you can, will you tell us more about your marriage, your situation, and how you may have come to suspect borderline personality disorder?
There are many other folks here, whom have chewed the same dirt as you, believe me, we know!
Meantime, take a look at the top banner up there, "Diagnoses Treatments, Tips & Tools"… and see the drop downs… also the "Groups" on the next bar down… take a look around, in the "Groups" there is a tab about tools specifically… I have the shortcut link here for you…

Again, welcome Tjgg!
